Specification of Letters Patent.

Patented July 7, 1914.

Serial No. 667,378. 1

To all whom it may concern:

Be it known that I, ELMER E. HAUER, a citizen of the United States, residing at Springfield, in the. county of Clark and State of Ohio, have invented certain new and useful Improvements in Turbines, of which the following is a specification, reference being had therein to the accompanying drawings. I 1

My invention relates to turbines and more particularly to a turbine for driving boiler tube cleaners adapted to follow the cleaner into a tube, although it may be used for other purposes.

The object of my invention is to provide an improved turbine of this class simple and compact'in construction, of few parts easily assembled and taken apart.

lVith these and other objects in view my invention consists of the constructions and combinations hereinafter described and set forth in the claims.

In the accompanying drawings which form a part of this specification Figure 1 .is a longitudinal section of a motor embodying my invention and shows a tube cleaner attached thereto. Fig. 2 is a section of 'a portion of the motor showing the front bearing with modified means for lubricating said bearing and this View further shows a drill head secured to the motor by a universal joint, and Fig. 3 is a cross-section taken on the line 33 of Fig. 1.

Like numerals represent the same parts in the several views.

In the drawings 1 represents a casing having an'integral head 2 at its front end and a removable head 3 at its rear end having a screw-threaded opening 1 to attach a supply conduit. Said head 3 projects forwardly within the casing 1 and is screwthreaded thereto at 5. A disk or partition 6 is preferably formed integrally with the head 3 and is provided with a rearwardly extending portion 7 to form a bearing for a shaft 8 and I preferably provide a removable bushing 9 for said bearing. A cap 9 closes the rear end of the bearing.

A hollow shaft or rotating member 10 is journaled in an opening through the front head 2, a removable bushing 10 being preferably provided as a bearing for same. Said shaft or member 10 projects rearwarclly in the casing and a disk or partition 11 is screw-threaded Within the shaft or maybe fixed to said disk in any suitable manner but I have shown the same as made integral therewith. The turbine wheel 12 is mounted on the shaft 8 and is preferably provided with a central'hardened portion 13 screw-threaded therein. It may be secured to the shaft in any proper way but I have shown the same keyed to the shaft by a key 14 against a shoulder on the shaft. The motive agent being introduced through the opening 4 passes through the usual inclined ports 15 in the partition 6 into the bucket 16 of the wheel 12 and is discharged therefrom through the opening 17 in the partition 11 and thence through the openings 18.

In Fig. 1 I'have shown a cleaner head the base 19 of which is screw-threaded to the end. of the shaft 10, said base being provided with openings 20 affording additional discharge. for'the motive agent; and in Fig. 2 Ihave shown adrill head with a universal coupling, the member 21 of which is screwthreaded to the shaft and provided with the openings 22 affording additional discharge.

It will be seen the hollow shaft 10 extends rearwardly past the ports 15 in the partition 6 and incloses the wheel 12 and the shaft 8 is secured to the shaft 10 by the partition 11 so that all said parts rotate with the wheel and arecarried by front and rear bearings as described.

The bushing 10 is provided with a flange 23 which extends between the front head 2 and a shoulder on the shaft 10 to take the forward thrust and I preferably provide a wearing ring 24 between said flange and shoulder and the bushing 9 is provided with a flange 25 to take the rearward thrust.

An opening 26 through the cap 9 registers with a conduit 27 in the shaft 8 and admits the motive agent to the rear bearing for the purpose of lubrication; and a screwthreaded grease cup or reservoir, 28 in the head 2 is provided with a screw plug 29 to force the lubricant through the openings 30 to the front bearing. shown means for lubricating the front bearing by admitting the motive agent to said bearing through theopenings 31.

Having thus described my invention I claim 1. In a turbine, a wheel having a hollow shaft forming a shroud for said wheel and member 10 to carry the shaft 8. Said shaft In Fig. 2 I have projecting therefrom to carry the discharge from said wheel. I I

2. In a turbine, a casing having. an integral front head with an opening therethrough, a bush bearing in said opening,-a wheel having a hollow shaft journaled in and projecting through said bearing with jecting forwardly from said wheel through an opening in said head and journaled therein, a tool secured'to said shaft having openings for the discharge of the motive agent from the wheel.

5. In a turb'ne, a casing having an in.- tegral front head and a removable rear head, a wheel having a forwardly and rearwardly extending shaft,'front and rear bearings for said shaft,'the forwardly projecting shaft being hollow and having openings to dis charge the motive agent from the wheel in front of said front head and meansto lubricate sa1d front and rear bearlngs.

6; In aturbine, a casing havln an 1n-' te gral front headand a remova 1e rear head, a wheel having a forwardly and rearwardly extending shaft, front and rear journal bearings for saine,. th rust bearings in the rear of the front head and in front of the rear head, the forwardly projecting shaft being hollow and having openings to discharge the motive agent from the wheel in front of the front head and means to lubricate said journal and thrust bearings.

7. In a turbine,,a wheel, a forwardly projecting hollow shaft, a rearwardly extending solid shaft, and a ported'partition to secure saidshafts together, said hollow shaft forming a shroud for said wheel.

8. In a turbine, a 'casingfa stationary ported partition, a wheel having "a hollow shaft forming a shroud for said wheel and ported partition, said' shaft projectingfore wa-rdly to discharge the motive agent from said wheel. V

' 9. In a turbine, a casing havinga front head with an opening therethrough, a' stationary ported partition, a wheelhaving a hollow shaft forming a shroud for said wheel and partition and projecting forwardly'through and being journaled in the i opening in said head and'adapted' to dis chargethe motive agentfrom the wheelin front of said head.

In testimony whereof I have hereunto I afiixed my signature in the presencefof two i witnesses. 1 'ELMER HAUER.
